CSK Auto Corporation Requests Additional One-Month Extension from New York Stock Exchange

PHOENIX--CSK Auto Corporation today announced it has submitted a request to the New York Stock Exchange (“Exchange”) for an additional one-month extension to file its 2005 Annual Report on Form 10-K (“2005 Form 10-K”) for its fiscal year ended January 29, 2006. As announced in November 2006, the Exchange had previously granted the Company a four-month extension until February 28, 2007 to file its 2005 Form 10-K with the Securities and Exchange Commission.

Although the Company has made substantial progress in its restatement, CSK Auto is seeking the additional one-month extension in order to complete its restatement process. The Company will communicate the decision of the Exchange as soon as practicable.

As previously announced, CSK Auto is in the process of restating its financial statements for each of the two fiscal years 2003 and 2004, selected consolidated financial data for each of the four fiscal years 2001 through 2004 and interim financial information for each of its quarters in fiscal year 2005. These restatements are being made to reflect matters reviewed in the course of an Audit Committee-led investigation of accounting practices and the resulting adjustments to prior period financial statements.

Portions of this release may constitute “forward-looking statements” as defined by federal law. Although the Company believes any such statements are based on reasonable assumptions, there is no assurance that actual outcomes will not be materially different. Any such statements are made in reliance on the “safe harbor” protections provided under the Private Securities Litigation Reform Act of 1995. Additional information about issues that could lead to material changes in the Company’s performance is contained in the Company’s filings with the Securities and Exchange Commission. The Company makes no commitment to revise or update any forward looking statement in order to reflect events or circumstances after the date any such statement is made.
